E: CONTENT
Grains as Energy-Giving Crops
Grain crops such as: 🌽 Maize 🍚 Rice 🌾 Millet contain carbohydrates. Carbohydrates give the body energy.
Tubers as Energy-Giving Crops
Tuber crops such as: 🍠 Yam 🌱 Cassava 🥔 Potato also contain carbohydrates.
Foods Made From Grains
Examples include:
- Pap.
- Rice meals.
- Corn flour.
- Bread.
Foods Made From Tubers
Examples include:
- Pounded yam.
- Garri.
- Fufu.
- Fried yam.
- Boiled potato.
Difference Between Grains and Tubers
Grains are mainly seeds. Tubers are enlarged underground parts. Both provide energy.
